The Zak Family of Companies

The Zak family of companies consists of two sister-companies that work hand-in-hand to add value to every project we undertake.  When you choose to work with one Zak company, you also get the expertise and resources of the other. We focus tightly on the needs of our clients as a whole, over the long-term, rather than taking a simple project by project approach.  Our level of dedication to building partnerships is why we have over 90% repeat clients — many for 20 years or more!

About Us

Synergy—

the blending of multiple elements to produce an effect greater than the sum of their individual effects.

That’s what you get when you select Heideman Associates or Franklin Mechanical, Inc.  These sister companies bring a superior blend of experience, services, and expertise—resulting in synergy that pays off in an outstanding project. 

Synergy in Staff Expertise. Our experienced management talent and seasoned field superintendents as well as key individuals for on-site labor have the autonomy and authority to do whatever it takes to get the job done on time and within budget. 

 Synergy in Access to Resources and Support.  As members of Zak Companies, Heideman Associates and Franklin Mechanical receive the same support and access to internal resources for education, networking, hardware, software, and technical support. Our BIM expertise and modeling capabilities are one and the same.  The result is a team effort that is seamless to our clients. 

 Give us the opportunity to demonstrate how well we can make it all add up to project savings for you!

Our History

Zak Companies, Inc.  was founded in 1991 by Robert Zak, Jr.  Over the past 31 years, we have grown to include five subsidiary companies, and over 300 employees.

Beginning with Heideman Associates in 1991,  Zak Companies began moving toward a design-build delivery model in the mid-90’s and soon added plumbing contractor, Franklin Mechanical, to complement our engineering services.  While each of these companies became individually well-established, they also began developing new ways for designers and contractors to collaborate, share expertise, and bring a broader perspective to each and every project.

In 2004,  Heideman Associates, in response to our clients’ needs, began offering commissioning services for building systems.  Expanding upon the basic functional testing services already offered, Heideman established an independent team of Commissioning Authorities and began offering full systems commissioning as a stand-alone service.  

As we enter our fourth decade of serving clients across the nation, Zak Companies looks forward to creating new milestones in the years ahead.

Mission Statement

We will provide the best services to meet our clients’ goals. We will be industry leaders in developing new design methods and standards. We will provide our clients with the most innovative, flexible, efficient and cost-effective systems within the budget of the project. Our standards will become the measure against which our competitors will be judged.

Our Clients

Zak Companies, Inc. has a wide-reaching and varied client base.  Our core clients span the healthcare, water/wastewater, industrial, pharmaceuticals, telecommunications, commercial, education, government, recreation and technology markets, and include some of America’s most well-known corporations.
